COPY-HOLDER.

SPECIFICATION forming part of Letters Patent No. 428,700, dated 'May 27,1890.

Application iiled February 25, 1890. Serial No. 341333. (No model.) I

T all whom it may concern:

Beit known that we, JAMES W. SNYDER and GUsTAvE H. GRABE, citizens ofthe United States, residing at Coudersport, in the county of Potter andState of Pennsylvania, .have invented a new and useful Copy-Holder, ofwhich the following is a specification.

rlhis invention has relation to copy-holders, and among the objects inview are to provide a simple and efficient copy-holder adapted to beoperated line by line as copied, the holder being operated by aconvenient key located at one side of the same.

A further object of the invention is to provide an efficient andconvenient means of introducing the manuscript between the feedrolls ofthe holder, and to avoid any breaking or bending of the same.

With the above objects in view the invention consists in certainfeatures of construction hereinafter specified, and particularly lpointed out in the claims.

Referring to the drawings, Figure l is a perspective of a copy-holderconstructed in accordance with our invention. Fig. 2 is a transversevertical section. Fig. Sis an end elevation. Fig. 4. is a detail intransverse section looking toward the ratchet.

Like numerals of reference indicate like parts in all the figures of thedrawings.

l represents any suitable base or standard, and from the opposite endsof the saine there rise slightly-inclined standards 21 which, near theirupper ends, are provided with elongated slots 3, and journaled in thesame is a roller 4, the trunnions 5 of which rest in the elongated slotsand are pressed upon by a bearing-block 6, between which and the upperend of the slot there is interposed a coiled spring 7.

Below the roller/i there is located the feedroller 8, the shaft of whichis j-pijojected beyond the standards 2 and at one side provided with acrank 9. The opposite end of the shaft is provided with a ratchet-wheel10, and said wheel is rigid and moves with the shaft. Beyond said wheelthe shaft vis provided with an oscillating disk 1l, said disk beingindependent of the shaft and provided upon its inner face with afeed-pawl 12, pivoted as at 13, and having its free end engaging theratchet and maintained in such engagement by means of a curved spring 14secured to the disk. At one side of the disk there is pivoted to thebase, as at l5, a keylever 1G, which near its free end is straddled byakeeper i7, and between the key-lever and 'base there is interposed aiiat spring 1S. A pitinan i9 connects the oscillating disk with thekey-lever, and bydepression of said lever the disk is oscillated in onedirection, and by the fiat spring under the lever'returned or oscillatedin the opposite direction.

It will be apparent from the foregoing description that by adepressionof the key-lever the pawl will serve to rotate theratchetwheel and the shaft upon which it is mounted one tooth to therear, which distance agrees with that between the lines of themanuscript, so that for every depression of the keylever the manuscriptis fed one line farther to the rear.

20 represents a feed-passage, the rearend of which is provided withlaterally-progecting feet 21, secured to the base by screws 22. Thefeed-passage is open at opposite ends, and the edges at the rear end areiiared, as at 23, so as to receive the manuscript readily. The passageprojects forwardly under the rolls, and is curved upwardly, as at 24,forming the letter J in cross-section, the mouth of the same terminatingat a point nearly opposite the point of contact of the rolls, so thatmanuscript introduced into the passage may be pushed forward and willhave its upper end guided between the rolls.

By operating the crank the manuscript Amay be fed any distance betweenthe rolls, or byl successive depressions of the key, as beforedescribed, the same is fed lineby line.

Having thus described our invention, what we claim is- 1. In acopy-holder, the combination, with opposite standards and oppositerolls, the upper one of which is spring-pressed upon the lower, of aratchet mounted rigidly upon the shaft of the lower roll, an oscillatingdisk mounted upon said shaft at one side of the ratchet, a pivoted pawlsecured to the disk and meshing with the ratchet, a spring formaintaining the saine in contact with the ratchet, a pivoted key-leversecured to the IOO hase@ Sprngfor raising the sinne, :ind a pitmanconnecting the key-lever with the oseillating disk, substantially asspecified.

2. In a eopy-holder, the combination, with two rolls, the upper one ofwhich is maintained in yielding Contact; with the lower, and means foroperating` the rolls, of a :mannseript-passage secured to the hasebetween the rolls, having si rear flared month and its forward end"upwardly curved in front of the rolls and termina-ting in L pointbetween the Sinne, substantially as specified.

In :L copy-holder, the standards mounted upon the base and carrying therolls, one of which is spring-pressed, combined with thekey-leverpivoted to the base and spring-supportethns shown, ratchet onone of the rolls, and :t disk located upon and rigid with the shaft :md:it one side of the ratchet, and :L

pnwl pivoted to the diek and engaging the rate]iet-connections betweenthe lever and the disk, as Set forth.

Llv. In L oopyholder, the combination, with the two rolls between whichthe eopy is passed, of the inminseript-pzt5sage in the forni of theletter .I in eross-Seetion, having its base seenred to the base of thecopy-holder and its front end curving,- upwardly and terminating at :Lpoint nearly opposite the point of eontaet of the rolls, :is set forth.

In testimony that we claim the foregoing as our own we have hereto aixedour signatures in presence of two witnesses.
